Professional Applications & Engineering Value

This 6-32 UNC flange locknut delivers exceptional performance in high-vibration environments where fastener security is critical. The distorted thread locking mechanism creates consistent interference fit that maintains clamp force without requiring additional locking elements. Manufactured from cadmium yellow-chromate plated steel, this nut provides superior corrosion resistance while the integrated flange distributes bearing stress across wider surface areas. Particularly valuable in aerospace assemblies, heavy machinery, and transportation equipment, this MS21042L-06 compliant component ensures reliable performance where safety and durability are paramount. The combination of Class 3B thread precision with pre-applied lubricant enables proper installation torque values while minimizing the risk of cross-threading in critical assemblies.

Specification Summary & Compliance

This flange locknut features 6-32 UNC coarse threads with Class 3B fit for precision engagement, manufactured to MS21042L-06 military specifications. The component maintains dimensional accuracy with 3/16" width across flats and 9/64" height, featuring a 0.244" flange diameter and 0.03" flange thickness. Compliance includes meeting relevant industry standards for aerospace applications, with right-hand thread orientation and external hex drive configuration. The cadmium plating provides environmental protection while maintaining electrical conductivity where required.
